LogProviders.GetEnumerator 方法

定义

命名空间:

Microsoft.SqlServer.Dts.Runtime

程序集:

Microsoft.SqlServer.ManagedDTS.dll

返回用于遍历 LogProviderEnumerator 集合的 LogProviders。

public:
 Microsoft::SqlServer::Dts::Runtime::LogProviderEnumerator ^ GetEnumerator();

public Microsoft.SqlServer.Dts.Runtime.LogProviderEnumerator GetEnumerator ();

override this.GetEnumerator : unit -> Microsoft.SqlServer.Dts.Runtime.LogProviderEnumerator

Public Function GetEnumerator () As LogProviderEnumerator

返回

LogProviderEnumerator

用于遍历集合的 LogProviderEnumerator。

示例

下面的代码示例使用GetEnumerator该方法创建一个LogProviderEnumerator，然后循环访问集合。

using System;  
using System.Collections.Generic;  
using System.Text;  
using Microsoft.SqlServer.Dts.Runtime;  

namespace LogProviderInfos_testing  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            // The package is one of the SSIS Samples. The package  
            // was modified in the designer to log to the SSIS log  
             // provider for Text files before being loaded  
            // for this code example.  
            string mySample = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx";  
            // Create the Application, and load the sample.  
            Application app = new Application();  
            Package pkg = app.LoadPackage(mySample, null);  

            // Get the LogProviders collection from the package.  
            LogProviders logProvs = pkg.LogProviders;  

            //Create the Enumerator.  
            LogProviderEnumerator myEnumerator = logProvs.GetEnumerator();  
             Console.WriteLine("The collection contains the following values:");  
            int i = 0;  
            while ((myEnumerator.MoveNext()) && (myEnumerator.Current != null))  
                Console.WriteLine("[{0}] {1}", i++, myEnumerator.Current.Name);  
        }  
    }  
}  

Imports System  
Imports System.Collections.Generic  
Imports System.Text  
Imports Microsoft.SqlServer.Dts.Runtime  

Namespace LogProviderInfos_testing  
    Class Program  
        Shared  Sub Main(ByVal args() As String)  
            ' The package is one of the SSIS Samples. The package  
            ' was modified in the designer to log to the SSIS log  
             ' provider for Text files before being loaded  
            ' for this code example.  
            Dim mySample As String =  "C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx"   
            ' Create the Application, and load the sample.  
            Dim app As Application =  New Application()   
            Dim pkg As Package =  app.LoadPackage(mySample,Nothing)   

            ' Get the LogProviders collection from the package.  
            Dim logProvs As LogProviders =  pkg.LogProviders   

            'Create the Enumerator.  
            Dim myEnumerator As LogProviderEnumerator =  logProvs.GetEnumerator()   
             Console.WriteLine("The collection contains the following values:")  
            Dim i As Integer =  0   
            While (myEnumerator.MoveNext()) &&(myEnumerator.Current <> Nothing)  
            Console.WriteLine("[{0}] {1}",i = Console.WriteLine("[{0}] {1}",i + 1  
            End While  
        End Sub  
    End Class  
End Namespace  

示例输出：

该集合包含以下值：
